>>44351844optitrack can support the openVR standard but VRC themselves only use openVR for the headset portion. Full body tracking in VRC is limited to IK tracking for the most part, where full body professional mocap tracks every bone at once. IDK if this is an issue with limited simultaneous inputs or something but VRC does not officially support anything other than what's listed here. I'm sure there are ways to jerryrig it together but it's not worth the effort especially when the jank is part of the fun.
